Abstract
Abstract Lower aliphatic glycosides are added to aqueous liquid detergents to reduce their viscosity and to prevent phase separation. The glycosides are represented by the formula R-O-(G) n where "R" is a C 2-6 straight or branched chain saturated or unsaturated aliphatic hydrocarbon group, O is an oxygen atom, G is a saccharide unit, and n is a number from 1 to 10. The glycosides comprise about 1 to 10 weight percent of the detergents.
